Abstract
In hemolymph, gut, and molting fluids of nymphal and adult Hyalomma (H.) dromedarii (Koch) and H. (H.) anatolicum excavatum (Koch) (family Ixodidae), the lipid classes were phospholipid (PL), cholesterol (CH), free fatty acids, triglycerides, and sterol esters, together with small amounts of mono- and diglycerides. PL, total sterols and percent CH contents were analyzed during specific physiological states of tick development. Hemolymph free sterols consisted exclusively of cholesterol. When fully fed nymphs and females dropped from the host, their gut PL and sterol concentrations were substantially higher than in host rabbit plasma and whole blood. Lipid concentrations on the day engorged nymphs dropped from the host, molting day and the female dropping day changed more consistently than for the other states. The results suggest that ticks have no requirement, and therefore lack the capacity, for sterol biosynthesis.
